Abstract
We report the measurement of the two-neutrino double-beta () decay of Mo to the ground state of Ru using lithium molybdate (\crystal) scintillating bolometers. The detectors were developed for the CUPID-Mo program and operated at the EDELWEISS-III low background facility in the Modane underground laboratory. From a total exposure of kgd, the half-life of Mo is determined to be years. This is the most accurate determination of the half-life of Mo to date. We also confirm, with the statistical significance of , that the single-state dominance model of the decay of Mo is favored over the high-state dominance model.
